I installed Wireshark v1.4.3
When I tried to capture EtherCAT packet from my Realtek NIC, I can not see the EtherCAT packet.
I only can capture DHCP protocol packet.
Should I have to config other option to capture EtherCAT packet?

According to http://www.ethercat.org/en/technology.html#3.1, EtherCAT uses either Ethertype 0x88A4 or UDP port 0x88A4. And at the link layer, it's just ethernet.So you don't have to do anything special to be able to capture EtherCAT packets. Take a look at http://wiki.wireshark.org/CaptureSetup/Ethernet for information on how to capture in different setups.
Regarding dissecting of the EtherCAT frame, it's done in a separate plugin, have you installed all the plugins that came with Wireshark?
